FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry. Method comprises descending into a casing of a pump with a submersible motor connected to a control station via a cable line consisting of current-carrying insulated conductors and an armored metal band wound on them, wherein the lower end of the armored band of the line is connected to the motor body and the upper end of the band is removed from the well and connected to the casing. Electrically conductive paste is applied to the contacting surfaces of these connections. In the cable line, consisting of individual cable sections, armored bands of adjacent sections are joined together by soldering or welding. Separate conductors can be used to connect armored bands.
EFFECT: effectiveness of protection and inter-repair period of well equipment are increased.
